Arturia KeyStep 37 MIDI Keyboard Controller and Sequencer - Manual (Page 27)

2.3. Using the arpeggiator
An arpeggio is a chord of which you repeatedly play the individual notes. It's what you hear
when you hold a chord on a guitar and pluck the strings from top to bottom or the other
way around. A major part of learning to play the guitar is figuring out how to play different
fingerpicking/arpeggio styles. The arpeggiator on the KeyStep 37 does all these things for
you.

The arpeggiator will not run if the sync selection switches are set to something other than internal
and no external clock is present.
2.3.1. Seq / Arp toggle switch
To use the arpeggiator you must first set the Seq/Arp toggle switch to Arp. The Seq position
selects the sequencer, which is covered in section 2.2 [p.20] .
2.3.2. Seq / Arp Mode encoder
Use the Seq/Arp Mode encoder to select one of the eight arpeggiator Modes: Up, Down,
Inclusive, Exclusive, Random, Walk, Pattern, Order.
The Modes are described in more detail in Chapter 5 [p.52]
